Plot synopsis: Magical, autonomous, all-powerful… Artificial intelligences feed our dreams as well as our nightmares. But while tech giants promise the advent of a new humanity, the reality of their production remains totally hidden. While data centers are concreting landscapes and drying up rivers, millions of workers around the world are preparing the billions of data that will feed the voracious algorithms of Big Tech, at the cost of their mental and emotional health. They are hidden in the belly of AI. Could they be the collateral damage of the ideology of “Longtermism” that has been brewing in Silicon Valley for several years?
